Abstract (en)

A monitoring system (200) for a dual-stage, pressure-activated, mixed fluid gas shock strut (100) , may comprise a controller (201), and a tangible, non-transitory memory (208) configured to communicate with the controller (201), the tangible, non-transitory memory (208) having instructions stored thereon that, in response to execution by the controller (201), cause the controller (201) to perform operations comprising receiving, by the controller (201), a primary chamber temperature sensor (202) reading, receiving, by the controller (201), a primary chamber pressure sensor (202) reading, receiving, by the controller (201), a shock strut stroke sensor (206) reading, and calculating, by the controller (201), an oil volume in a primary chamber (130) of the shock strut (100). The instructions may cause the controller (201) to perform further operations comprising calculating, by the controller (201), a number of moles of gas in a primary chamber (130) of the shock strut (100) and calculating, by the controller (201), a number of moles of gas in a secondary chamber (140) of the shock strut (100).
